In Mexico May 27, 1947 I This invention relates to a valve structure wherein the valve per se and its casing are provided with openings or ports for directing fluid to selected pipe lines leading from the casing.

The object of the invention is to provide a valve structure wherein the valve per se can be slightly removed from its seat to permit of its being 2 Claims. (Cl- 251-87) axially moved to direct the flow of fluid to one or several openings to feed fluid to the pipes and lowered and locked in its seat when the selection of flow has been made.

A further object of the invention is to provide in a valve structure means for slightly raising the valve per se from its seat, associated with separate means for axially moving the valve to register with selected openings for flow of fluid, and after the selection is made, lower the valve in its seat to lock it in the selected position.

In the drawings:

Figure 1 is a perspective view of the improved valve structure.

Figure 2 is a central vertical section of the valve structure.

Figure 3 is a horizontal section on the line 33 of Figure 2.

In the drawings represents a two-part casing, the lower cylindrical section 2 is conical internally to provide a valve seat 3 and from its periphery extend pipes 4--5 and 6, and a chamber I, provided with a nipple inlet 8 and three inlet ports 9, I0 and H.

An upper section l2 of the casing fits over, and is bolted to the lower section 2 and projecting from its upper end is an externally and internally threaded nipple l3.

Surrounding the valve seat is a gasket I4 and fitting in the valve seat 3 is a rotatable hollow valve l5 formed with openings a-b, c and d.

In the center of the lower valve section 2 is valve l5 provided with a well l6, well l6 having a bottom formed with a square opening l1, and

below the well is a cap l8 and in the top of the valve is a threaded opening l9.

A valve stem 20 having a square end 2| fits in the square opening IT in the bottom of the well, and surrounding this stem is a sleeve 22 threaded at 23 to engage the internal threads on the nipple I3. The lower end of the sleeve is provided with a collar or nut 25, and between the nut and the well is a washer 26. A threaded plug 21 is mounted on the sleeve and engages the internal threads inthe opening l9. Thus the nut or collar 25 is confined between the bottom of the plug 21 and the well, to hold the sleeve in position in the casing.

The'top of the plug 21 is threaded at '28 to receive a threaded packing nut 29; A packing nut 30 is mounted on the sleeve 22 and enga es the threaded nipple l3 and at the upper end of the sleeve, above the packing nut 30 is a handle 3| to rotate the sleeve, to lift the valve from its seat, as will be explained later on. v

The upper end of the stem 20 is provided with a hand wheel 32 by means of which the valve l5 can be rotated to register with selected openings a, b, c and din the casing.

In operation, assume the parts are in the position shown in Figure 3 and fluid is fed to the receiving chamber 1. The fluid will pass through openings I0 and a and openings H and d to the valve. At this time openings 9bc and pipes 4, 5 and 8 are closed, and the valve is locked seated in the lower section 2 of the casing.

If it be desired to position the valve to direct the fluid through pipe 4, the handle 3| is first turned, which through the threaded connection 23, the sleeve 22 and the valve I5 are raised, sufficiently to break the seal with the valve seat. Then the hand wheel 33 and stem 20, which directly carry the valve l5, are rotated to register openings 9 and d and openings II and c and opening a and pipe 4. Then the handle 3| is reversed to engage the valve with its seat.

If it be desired to feed the fluid from chamber 1 to pipe 5, the lever 3| is turned to lift the valve from its seat, and the hand wheel 33 is turned to rotate the valve to register openings 9 and v0 and and b and opening a of the inlet of pipe 5. When registration of the openings is made, the handle 3| is turned to lower and look the valve in its seat.

If fluid is to be directed through pipe 6, the valve is lifted from its seat and the hand wheel 33 is turned to register the openings 9 and ba and opening of .pipe 6.

To determine the selected registration of the various openings, the handle 33 is provided with indicating indicia, which may be in the form of slight projections, each indicating one of the pipes 4, 5 and 6.

From the foregoing description it is evident I have provided a unique valve which may be conveniently used to control the flow of fluid in selected pipes.

I claim:

1. A valve comprising a valve casing having an internally threaded opening and a conical valve seat and at least one opening therethrough, a gasket lining said valve seat and having at least one opening coinciding with said seat open-l ing, a sleeve having external threads to engage the threaded opening in said casing, a hollow conical valve plug carried by said sleeve in said casing for cooperation with said gasketed valve seat, said plug having at least one radial opening therein for cooperation with the seat opening, a handle on said sleeve. beyond said casing, a shaft journalled in said sleeve and keyed to said plug beyond the inner end of said sleeve, and a second handle on the outer end of said shaft beyond the outer end of said sleeve, whereby operation of said first handle will axially move said valve plug relative to said gasketed seat, and actuation of said second handle when said plug is retracted from said seat will rotate said plug relative to said seat. p

2. A valve as set forth in claim 1 wherein-said seat and plug comprises a plurality of openings trusions are provided on said handwheel to respectively identify the openings in said valve plug.
